:useful Improvements in Universalaloint Couplings, ication. c

The invention relates 1n general to un1- versaljo1nt couplings, designed1n particular of which the following is a speci Ato prevent theaccumulation ofgrit, dust and other matter upon thejoint and therebywear the same, and secondly to provide a housing whereby any oil orlubricating ma terial used upon the joint may be confined within thehousing to prevent the scattering thereof and also tofurther assist inlubricating.

Referring nowI to the drawing, Figure 1 represents a longitudinalsection of my improved housing with universal joint and shaft couplingtherein. Fig.` 2 is a top plan view of Fig. 1 with parts completed.lTig, 3 is a section onthe line 343 of lTig. 2.

Referring now more particularly tot-he drawing, 5 is a universaljointshaft having socket joints G and 7 constituting one part of a balland socket joint formed integral at either end thereof and adapted tocooperate with ball joints 8 and 9, which are connected to counter'shafts 10 or to such other parts as may be desired. Theicountei" shafts10v have a bearing within the ball bearing casings 11.

rl'he ball and socket joint construction herein shown is of aparticular' construction, constituting no part of this invention vand Aneed not, therefore, he described more in till detail. j 1 j f 'ltheouter ends of the hearing cases 11 are internally threaded as shown at12 and 13 and to these ends are connected annular at-y taching or guardmemhers 1QIl and ltL which are provided with threaded portions 1d "iadapted to cooperate with the interiorly threaded ends 12 and 13 of theball bearing casings 11. The annular attaching or guard member 12a isprovided with a partrspherical surface 1t?, while the annular attachingor guard member 13 is provided` with an annular lla surface 16 uponwhichis slidu ably mounted a ring 1'? having a parti-- spherical surface 1@similar to the surface 'lli en the attaching inemher 12H. The attach ingmembers 12l and 13 are rio-idly secured te the bearing easings and.prelerahly pro-l ject, for a short distance, over the universal joints.

'lhe invention includes avhousing or covering designated as a whole at19, for these` universal ball and socket joint members and universaljoint shaft 5, preferably consisting of two parts 2O and 2l havingintegral regis tering lugs 22 formedt'hereon adapted to be securedtogether by means of the screws or bolts 28, or by any other well knownmeans. The two parts of the housing are interiorly beveled at theirouter ends, conforming to the beveled or curved surfaces 15 and 18, asshown at 241, to lit theI beveled or curved end ofthe attaching member12a and over the sliding collar 17 whereby when the two parts ofthe-housing are mounted upont-he attaching members. and secured togethera complete casing or housing will be formed for the universal jointconnections that will keX- L clude any dirt, dust or other mattei'therefrom. versal joints relative to the other results in a slightincreaseof distance between the two attaching members and to provide forthis movement the collar 1T is devised-whereby if the universal jointmember 8 moves relative to the universal joint member 9, the collar 17may have a sliding movement on the flat surface 16 of the attachingmember 13 whereby the universal joint coupling will have a free movementand still the dust and other matter will be excluded therefrom. 'lhehousing is preferably made in two parts and secured to the attachingmemberswith-y the joint or meeting edges of the housing in asubstantially horizontal position whereby any oil, grease, or othermatter which may collect therein will not leak out. llor this lreasonthe housing also serves to retain all oil or grease, which otherwisewould be lost, within the housing for the purpose of further lubricatingthe universal joint cou pling..` lt can be plainly seen 'that with ahousing of this character no dust. or other matter can sift into theball hearings 25 nor to any other of the moving parts of the joint.

its means for preventing the possible .movement or rotation of thehousing relative to the attaching members, l provide a clip-itil securedto the hall, hearing casing l1 in any suitable manner and adapted toproject i to a clip 2l secured to one part of 'the housing, whereby anyrelative rotating The movement of one ofthe uniltlti movement 'betweenthe hearing casing andv 'the is prtrvenotedr vsa vThe particular designor contour of the outer surface of lthe housing is immaterial, and insomeA instances it `,night not be necessary to employ the sliding ring17 on the guard member 13a.

Therefore Without limiting the invention to the particular detailedconstruction herew in shown and described, I claim:

1. In a universal-joint coupling, the com bination of a pair of shafts,a universaljoint connection between the adjacent ends of said shafts,bearing casings for said shafts, attaching members secured to saidbearing casings, one of said attaching members having a partiallyspherical surfacethereon, a ring slidably mounted on the other of saidattaching members and provided With a partially spherical surface, and ahousing for said universal-joint connection between said attachingmembers and mounted upon one of said members and upon the ring of theother of said members with capacity for both angular and longitudinalmovement relative thereto, substantially as described.

2. In a universal-joint coupling, the combination of,a pair of shafts, auniversaljoint connection between the adjacent ends of said shafts,bearing casings for said shafts, attaching members secured to saidbearing casings, one of said attaching members having a partiallyspherical surface thereon, a ring slidably mounted 'on the other of saidattaching members and provided With a partially spherical surface, ahousing for said universal-joint connection between said attachingmembers and mounted upon one of said members and ing casings for saidcounter-shafts, attaching members secured to said bearing casings, oneof said attaching members having a partially spherical surface thereon,and a ring slidably mounted on the other o f said attaching -members andprovided with a partially spherical surface, and a housing for saiduniversal joints and universal-joint shaft between said attachingmembers and mounted upon one of said members and upon the ring of theother of said members with capacity for both angular and longitudinal' lmovementrelative thereto, substantially as described.
